As I got rid of some final hard coded IPv4 stuff, earlier this month I said good-bye to Ziggo cable internet.
Today, the xs4all ADSL line finally got disconnected as well:
My old trusty Fritz!Box 7340 showing ADSL got disconnected for good on 20161217
Which means that the years of running an xs4all DSL connection over mxStream, KPN FAST ADSL and xs4all ONLY are over. Oh the days:

Some of the [Wayback] Ken Thompson – Wikiquote entries come from a great [Wayback] 1983 ACM Turing Award Acceptance Lecture [Wayback] “Reflections on Trusting Trust”.
That lecture used to be on http://cm.bell-labs.com/who/ken/trust.html
But it isn’t, and was not in the WayBack machine and neither in the Google Cache [Archive.is] because of the [Wayback/Archive.is] robots.txt. Historic link rot galore!
Edit 20210728: by now it is in the Wayback machine again; the earliest archived copy is from 2001, it also shows that as of april 2015 it is gone from the bell labs server.
The lecture is about [Wayback] compiler viruses and viruses actually did this at least a few times: Wayback: Delphi in 2009 and to [Wayback] XCode in 2015.
A few nice links from [Wayback] ACM Classic: Reflections on Trusting Trust – Google Groups though:
And archived versions of (I hope accurate) copies of the article:
Finally I found a PDF copy of the original ACM prints that Greg Ganger of Electrical and Computer Engineering at Carnegie Mellon University has online. It’s archived too.

Time after time issues pop up related to MAC addresses that start with a4 or a 6.
[WayBack] nanog: Forwarding issues related to MACs starting with a 4 or a 6 (Was: [c-nsp] Wierd MPLS/VPLS issue)
The underlying issue has to do with switches interpreting too much information of (un)encrypted traffic and dropping them because they wrongly think it’s plain ethernet traffic they need to handle.
MAC addresses starting with a 4 or 6 have have a common bit pattern (likekly that fails with 12 and 14 as well) that cause failure in certain network equipment that’s hard to trace as there is limited.
[WayBack] Christian Vogel – Google+ (Physics, Electronics, Software) explains this way better at [WayBack] When your MAC address starts with 4 or 6, weird things can happen and it’s not always fixable… – Kristian Köhntopp – Google+:

I totally missed this because most of my WayBack activity is through the JavaScript buttons on my Chrome toolbar, so here it is:
A month ago, the WayBack machine introduced a new beta that allows for searching inside the archives.
Some links:
There actually seem to be two betas going on at the same time:

[WayBack] Schlechte Nachrichten für Fritz!box User: http://nic.box/ Euer http://fritz.box ist nicht mehr das, was es sein sollte. EDIT: Muahahaha … – Kristian Köhntopp – Google+
Now there is http://nic.box/ for the new [WayBack] box top level domain and AVM does not yet have the pre-registered fritz.box there effectuated (because .box is not in final registration state yet).
Kristian:
Schlechte Nachrichten für Fritz!box User: http://nic.box/ Euer http://fritz.box ist nicht mehr das, was es sein sollte.
EDIT: Muahahaha
kris@h1755802:~> host fritz.box
fritz.box has address 127.0.53.53
fritz.box mail is handled by 10 your-dns-needs-immediate-attention.box.
The joke is in the cryptic “your-dns-needs-immediate-attention” and usage of 127.0.53.53. to indicate a gTLD name collision.
Chrome knows about ICANN though and explains it in a slightly more readable form when browsing to http://fritz.box (:

If ever on openSuSE Tumbleweed you get an error ImportError: No module named pkg_resources then check you have the installed the python-setuptools package it is different from python3-setuptools which was installed by default but is not the default python used.
This is how to install it:
zypper install python-setuptools
Tools like speedtest-cli require it.
The odd thing: on a Mac, the homebrew speedtest-cli installed and ran with no additional packages needed:
retinambpro1tb:tmp jeroenp$ brew install speedtest-cli
==> Downloading https://github.com/sivel/speedtest-cli/archive/v0.3.2.tar.gz

(this is on one of my fiber connections back when it was 50/50 megabit).
Note that for both the web interface of speedtest.net and command-line versions (like Python based speedtest-cli) sometimes needs some fiddling with chosen servers and repeated measurements to get a consistent average as quite some factors can influence the measurements.
For my home location, this one gives me the most consistent results for my fiber connections (they’re so good and reliable that I don’t have ADSL or cable any more):
speedtest-cli --server 3629
You can get the list of servers ordered by increasing distance using this command:
speedtest-cli --list | head -n 20

I just blocked these IP subnets on my routers:
Within a day they managed to get 60+ IP addresses from these subnets into my port-scanner blacklists because of suspicious port scanning activities.
They mostly belong to Whg (International) Limited, Gibraltar and Whg (International) Limited, United Kingdom which seem to be related to William Hill Organization Ltd, United Kingdom that I just blocked before.
If the situation continues I’m going to block the 95.131.184.0/26 superblock as well:

TL;DR: OpenSuSE Tumbleweed – after installing from ISO, be sure to disable/remove the ISO repo.
A while ago I had a weird thing on my OpenSuSE Tumbleweed system while upgrading (yes, zypper dist-upgrade is the recommended way to update Tumbleweed): it would complain in this way zypper dup indicates python3-urllib3-1.16-1.1.noarch requires python(abi) = 3.5:
# zypper dup Warning: You are about to do a distribution upgrade with all enabled repositories. Make sure these repositories are compatible before you continue. See 'man zypper' for more information about this command. Loading repository data... Reading installed packages... Computing distribution upgrade... Problem: python3-urllib3-1.16-1.1.noarch requires python(abi) = 3.5, but this requirement cannot be provided Solution 1: Following actions will be done: deinstallation of python3-urllib3-1.15.1-2.1.noarch deinstallation of python3-wheel-0.29.0-2.1.noarch deinstallation of speedtest-cli-0.3.2-4.3.noarch deinstallation of python3-six-1.10.0-4.1.noarch deinstallation of python3-pycparser-2.14-2.1.noarch deinstallation of python3-pyasn1-0.1.9-2.1.noarch deinstallation of python3-pyOpenSSL-16.0.0-3.1.noarch deinstallation of python3-idna-2.1-1.1.noarch deinstallation of python3-chardet-2.3.0-1.4.noarch Solution 2: keep obsolete python-cupshelpers-1.5.7-7.2.noarch Solution 3: break python3-urllib3-1.16-1.1.noarch by ignoring some of its dependencies Choose from above solutions by number or cancel [1/2/3/c] (c):
What eventually – with help from the excellent help by DimStar on the #openSUSE-factory IRC channel – led to the solution was the part Solution 2: keep obsolete python-cupshelpers-1.5.7-7.2.noarch.
But first let’s look at the installed versions and repos:
